Abstract :
A comparative analysis is presented of the signal-subspace eigenvalues of a conventional covariance matrix and a covariance matrix after a spatial smoothing preprocessing procedure is performed. This comparison clearly demonstrates the advantages and disadvantages of the spatial smoothing technique.
